Description
図2に示すような外形の、コージェライト系酸化物セラミックス原料及び炭化珪素系非酸化物セラミックス原料にバインダーとしてメチルセルロース(MC)の成形助剤を用いて作製したハニカム成形体〔(コージェライト系酸化物セラミックス成形体:外径×流路長:106mmφ×220mm、セル数:93セル/cm2、隔壁厚み:64μm)、(炭化珪素系非酸化物セラミックス成形体:外径×流路長:35mm(断面が正方形)×330mm、セル数:31セル/cm2、隔壁厚み:381μm)〕を用意した。用意したハニカム成形体(担体)について、図4に示すように、下部から上方向に向けてセル内部に水蒸気(温度:100℃)を通過させることによりハニカム成形体1を加熱した。なお、コージェライト系材料については水蒸気量を50kg/hrとし、一方、炭化珪素系材料については水蒸気量を20kg/hrとし、各材料の予熱タクトタイムを20秒以下に調整した。
実施例1と同一材料及び同一形状のハニカム成形体を作製し、実施例1と同様にしてハニカム成形体を加熱した。ハニカム成形体の温度に対するハニカム成形体の強度変化を図5に示す。図5からわかるように、ハニカム成形体が加熱されハニカム成形体の温度が50℃を超えると、ハニカム成形体の強度が増大することが判明した。これは、加熱により、ハニカム成形体中のメチルセルロースなどのバインダーがゲル化することにより、ハニカム成形体の強度が上がったものと考えられる。したがって、その後に電磁波乾燥すれば、変形や切れの発生が生じずに品質の良好なハニカム乾燥体を得ることが可能である。
実施例1と同一材料及び同一形状のハニカム成形体を作製し、実施例1と同様にしてハニカム成形体を予熱し、ハニカム成形体全体を均一温度に加熱した。次いで、このように予熱したハニカム成形体について、マイクロ波の半減深度を測定した。得られた結果を図6に示す。図6の結果から、ハニカム成形体の温度が上昇するにつれてマイクロ波の浸透深さが深くなっていることがわかる。このことから、ハニカム成形体を予熱した後に電磁波乾燥すると、予熱しない場合に比べてハニカム成形体の均一乾燥が可能となることがわかる。なお、実施例3においては、図7に示す連続式マイクロ波乾燥装置を使用し、周波数2.45GHzのマイクロ波を出力密度5kW/kgで約200秒間照射して乾燥を行った。また、この連続式マイクロ波乾燥装置内のハニカム成形体の送り速度は、0.32m/minとした。その結果、変形や切れが発生しない品質の良好なハニカム乾燥体を得ることができた。
